In addition to higher operating costs, there will be the expense of adding thousands upon thousands of chargers at Post Offices across the country. Not to mention replacing batteries every few years at thousands a pop.
Then there is the fact that many - if not most - delivery routes exceed the average range of electric vehicles.
This is just politics infringing on the operation of a government agency, much as the military is being forced to go “green”.
How much to discard the batteries???
